Ensure that your Syslog server(s) will accept Debug messages. All
■
Syslog messages the switch generates carry the configured facility. All
Syslog messages resulting from debug operation carry a "debug" severity.
If you configure the switch to transmit debug messages to a SyslogD
server, ensure that the server's Syslog application is configured to accept
the "debug" severity level. (The default configuration for some Syslog
applications ignores the "debug" severity level.)
A reboot temporarily suspends Syslog logging. After a reboot, the
■
switch suspends configured Syslog logging for 30 seconds.

connecting ports. If a link LED fails to light when you connect the switch to a
port on another device, do the following:
1. Ensure that the switch port and the port on the attached end-node are
both set to Auto mode.
